?Your iris is ?the colored circle around your pupil, and every person's irises contain unique and detailed patterns of pigment and biostructures.

Hundreds of millions of people around the world have been entered in iris recognition systems, for purposes both convenient (like passport-free border-crossings) and legal (some national ID systems based on this technology are being deployed).

Iris recognition technology is super fast, and incidents of false matches are very rare, two more big reasons why iris scanning is gaining popularity around the world.

People with normal color vision agree that strawberries are roughly the same color as fire engines and rubies - they're all red. But could it be that what you call "red" is someone else's "blue"?

Based on older models of color perception, vision scientists always thought the answer to this question was "no". But new research is changing the minds of the scientific community. One person's red might actually be another person's blue and vice versa, the scientists said. You might really see strawberries as the color someone else calls blue, and the ocean as someone else's red!

The highest visual acuity (AKA best eyesight) ever recorded was actually in an unnamed Australian Aborigine man, part of a 1979 study that found Aborigines have much better eyesight on average than Europeans do. His visual acuity was 6/1.5, meaning that he could read an eye chart from 6 meters away as well as someone with "normal" vision could read it from 1.5 meters away.

Researchers believe that his visual prowess was due partly to genetics, and partly to using his distance vision so much - the man was a hunter in his community, and spent much of his time scanning long distances for minute signs of game.

Doctors from a number ophthalmology schools are reporting that Google Glass significantly reduces peripheral vision, blocking as much as 10 degrees of wearers' field of vision.

Dr. Tsontcho Ianchulev, lead researcher, was inspired to study the issue when he almost got into a car accident while wearing Glass himself.

Reduced peripheral vision is a serious problem when you're behind the wheel, or even just walking around. Seeing movement in your peripheral area generates an alert to possible danger and is the key to safely navigating the world.

The researchers let Google know about the problem, and it looks like a makeover is in store for Glass.
